5x + 2y = 20

6x + 5y = 24

Answers

Answer 1

Answer:

(4,0)

Step-by-step explanation:

Let's solve your system by elimination.

5x+2y=20;6x+5y=24

Multiply the first equation by 5,and multiply the second equation by -2.

5(5x+2y=20)

−2(6x+5y=24)

Becomes:

25x+10y=100

−12x − 10y = −48

Add these equations to eliminate y:

13x = 52

Then solve13x=52for x:

13x=52

(Divide both sides by 13)

x=4

Now that we've found x let's plug it back in to solve for y.

Write down an original equation:

5x+2y=20

Substitute 4 for x in 5x + 2y = 20:

(5)(4)+2y=20

2y+20=20 (Simplify both sides of the equation)

2y+20+ −20 = 20 + −20 (Add -20 to both sides)

2y = 0

(Divide both sides by 2)

y=0

Mr. Gardner is making 6 treat bags. He has 185 chocolate-covered raisins to share evenly among the treat bags.
How many chocolate-covered raisins will be in each treat bag?
How many chocolate-covered raisins will be left over?

Answers

Answer:

30 chocolate covered rasins

5 left over

Step-by-step explanation:

Step 1: 185 Divided by 6 and that gets you 30, and some left over.

Step 2: Do 6 x 30 and that gets 180

Step 3: Do 185 subtract 180 and then you get 5

Step 4: So 30 chocolate coverd raisins will go in each bag, and 5 will be left over.

sarah used 2.5 cups of cheese in a dish that serves 10 people amyn used 1.6 cups of cheese in a dish that serves 8 people how much more cheese is in one serving of sarahs dish

Answers

Answer:

[tex]\frac{1}{20}[/tex] more cheese in Sarah's dish than Amyn.

Step-by-step explanation:

To find this, we need to get the two fractions, [tex]\frac{2.5}{10}[/tex] and [tex]\frac{1.6}{8}[/tex] to a common denominator. The closest one is a multiple of 4 for [tex]\frac{2.5}{10}[/tex] and a multiple of 5 for [tex]\frac{1.6}{8}[/tex] .

This makes both fractions much more comparable, and we have

[tex]\frac{10}{40}[/tex]  for Sarah's dish

[tex]\frac{8}{40}[/tex] for Amyn's dish.

Knowing Sarah has [tex]\frac{2}{40}[/tex]'s more cheese in her dish, we can still simplify, so after dividing 40 by 2, we get [tex]\frac{1}{20}[/tex], the simplest form of how much more cheese Sarah has in her dish than Amyn,

Answer:

Step-by-step explanation:

2)  r = 16/2 = 8 cm

Area of top and bottom = 2*πr²

                                        = 2 * 3.14 * 8 * 8

                                       = 401.92 cm²

Midlle part = h * πd

                 = 6 * 3.14 * 16

                = 301.44 cm²

Total = 401.92 + 301.44

        =        703.36 cm²

3) Area of front and back = [tex]2* \frac{1}{2}*b * h\\[/tex]

                                         [tex]= 2*\frac{1}{2} * 3 * 4\\\\= 12 cm^{2}[/tex]

Area of bottom = length * breadth

                           = 12* 3

                          = 36 cm²

Area of left =  12 * 4

                  = 48 cm²

Area of right = 12 * 5 = 60 cm²

Total = 12 + 36 + 48 + 60 = 156cm²

Answers

Answer:

x = 5 (see below)

Step-by-step explanation:

Combine like terms by subtracting on both sides:

25 + 8x = 5 + 12x

20 = 4x

Then divide:

20 = 4x

5 = x

Move the variable to the left side of the equation:

x = 5

The answer would be x=5
